In September, NOSAMS joined colleagues at UC Irvine and Ottawa to co-host the second MICADAS Users Workshop. The meeting brought together representatives from 22 laboratories to share practical experience, discuss common challenges, and develop best practices for more reliable and comparable radiocarbon measurements.
NOSAMS contributed operational insights while learning from other facilities. We will also lead a collaborative effort focused on measurements of differently sized graphite samples. This work, along with ongoing efforts to improve data reduction and reporting, will help us continue providing users with robust and transparent results.

NOSAMS has expanded its dissolved inorganic carbon (DIC) capabilities with the completion of a second REDICS (Rapid Extraction of DIC System) line. Our original REDICS system continues to produce highly reliable, high-quality data. The new system is interfaced with a custom 12-port CO₂ storage and graphitization system that splits the CO₂ generated by REDICS, storing an aliquot for ¹³C analysis and graphitizing the remainder for radiocarbon analysis.
The new line accommodates 10 different sample volumes, providing greater flexibility for samples with variable DIC concentrations, such as groundwater. This complements the original system, increasing our capacity and representing the first new hydrogen-reduction graphitization line built in-house in 20 years.

New GO-SHIP samples arrived from tropical North Pacific
A new batch of seawater samples has arrived at NOSAMS from the recently completed Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) expedition along the P04E transect in the tropical North Pacific.
NOSAMS was founded in part to spearhead the analysis of Δ14C dissolved inorganic carbon (DIC) from repeat hydrography cruises. The data, archived in the publicly accessible CLIVAR and Carbon Hydrographic Data Office database (CCHDO) have become an invaluable resource for tracking circulation, ventilation, and changes in the global carbon cycle over time.
The P04E line was last occupied in 1989. Revisiting this transect more than three decades later provides an opportunity to compare radiocarbon distributions across a full generation of ocean change, offering new insights into how the tropical North Pacific has evolved since the late 20th century.
We look forward to adding these new measurements to the long-term GO-SHIP record and continuing to support the global oceanographic community with high quality radiocarbon data.

Ever wonder what happens to samples before they’re analyzed?
At NOSAMS, organic carbon samples are carefully pre-treated using either acid-base-acid (ABA) methods or acid leaching to ensure accurate results. For select samples, we use our automated OCtoPuS — the Organic Carbon Pretreatment System.
Curious to see how it works? Watch OCtoPuS in action in this short video.

Sue Handwork, Al Gagnon retiring
After a combined 83 years of service, NOSAMS administrator Sue Handwork and prep lab manager Al Gagnon are concluding their distinguished careers at NOSAMS. Al retired earlier this year, and Sue will soon follow. Over the years, many of you have shared how Al and Sue have shaped your experiences at NOSAMS, whether guiding you through the art of flame sealing or helping you navigate complex university payment systems.
Please join us in congratulating Sue and Al as they embark on their next chapters.
